The Eastern Caribbean Central Bank (ECCB) was established in October 1983. It is the Monetary Authority for a group of eight island economies namely - Anguilla, Antigua and Barbuda, Commonwealth of Dominica, Grenada, Montserrat, St Kitts and Nevis, Saint Lucia, and St Vincent and the Grenadines.

The Agreement establishing the ECCB as the monetary authority for the eight ECCB participating governments, was signed on 5 July 1983 in Trinidad and Tobago. The ECCB was officially commissioned on 1 October 1983, replacing the Eastern Caribbean Currency Authority (ECCA) which was established in March 1965.

The primary objective of the ECCB is to maintain the stability of the Eastern Caribbean Currency and the integrity of the banking system.
